BEIRNE GOB-DON, JR., OF U'IICA, YORK.

To all whom t mag/concern:

Be it known that I, ABEIRNE GORDON, Jr., of Utica, inthe county `ofOneida and State of New York, have invented certain new and usefulImprovements in Protecting Devices Machines; and I do` forCotton-Spinning l hereby declare 'that the following is a full, clear,and exact, description thereof, which will enable others skilled.V inthe art to which it appertains toA make and use 4the same, referencebeing had to the accompanying draw ings, and to the reference numeralsmarked thereon, which' form part of this specifi cation.Nv f 'lvMypresent invention is a protecting device for cotton spinningmachines.

In the ordinary cotton spinning machine orf-spinning mule the threads ofcotton or yarn come from the vdrawing rollers tothe spindles mountedupon Va carriage alter.- nately moving from and toward the rollers, andsuccessive lengths of the Vthreads are alternately drawn4 out andtwisted by'` the very rapid rotation of the spindles while the carriagemoves from the drawing rollers, and then the lengths of twisted cottonare wound onto the cops upon the relatively slowly rotatingspindleswhile the carriage moves back toward the drawing rollers-Winding up onto the cops the length that has just been drawn andtwisted. During the drawing, twisting'or spinning operation .proper thethreads pass over the counterfaller Vwire or guide positioned above thespindles so that the cotton will be twisted by the action of thespindles" and not wound up thereon upon the cops in vprccessfof Inakingupon the spindles. But `during the winding operation the faller wire orguide' passes downwardly and then upwardly beside the cops so as toguide the threads of respective cops. The result of these operations isthat cops or cigarshaped rolls of spun cotton are gradually.

formed upon the spindles. These cops at all stages of their formationhave coneshaped tops upon which are wound successive layers of cottonuntil the cops reach4 the proper height. This gradual building' up from`the bottom results in completed before the upper portion, so that theouter threads upon the lower portion of the cop areV exposed to the airfor a long time before the cop is completed.

lower portion of the cop during the spin- Y ning operation causes theouter threads to become dirty, dark or smoky. This dirt or other foreignsubstance 'must be absorbed from the air since the cops are not handledby the operatives and do not come in contact with any part of themachine. Furthermore, I have found that the cotton thus exposed upon thecops during the spinning operation becomes dirtier than does the cottonupon cops standing still in the same room for a similar space of time,and also becomes dirtier than does the cotton upon cops left upon thecarriage so as to be subjected tothe back and forth movement of saidcarriage, but disconnected from the mechanism of the carriage so as notto have the rapid rotating movement incident to spinning. F rom thesefacts, I concluded that'the excessively rapid absorption of dirt orother foreign matter bythe exposed cotton from the air during thespinning operation was due in some way to the very rapid rotation ofthe' copsduring the twisting or spinning operation proper, at which timethe rotation of the spindles is usually several thousand times a minute.My theory is that this rapid rotation of the cops produces in some wayair currentswhich drawrtoward the cops any dirt or other foreign matterthat may be iioating in the air near the machine, and the' dirt thusattracted to the cotton adheres thereto, resulting in the surface of thecotton becoming gradually darker as their formation progresses. :Thedirt thus settling upon the cotton at this stage of its manufacturecannot be removed, nor the cotton cleansed therefrom, but is permanentlyinjured for many ordinary purposes and for most line work, andaltogether has a greatly depreciated value. The dirt or foreignsubstance here referred to is not so muchl the readily discerniblestreet dirt or dirt from a manufacturing Vquarter which may be kept fromthe spinning room with ordinary care, but is more particularly the veryfine black or dark dirt or matter, such as is `suspended in the air .ona smoky day,

from operative position upon the descent off said faller guideincidentto the winding opin the course of their manufacture, and thethis purpose by the pro-VV accomplishing of viding of protectors orshields about the cops. These protectors are so arranged and the copsand l find protectors along both sides of the row of cops upon thespinning mulevery effectively vprevents the cops from becoming dirty lordarkened as hereinabove mentioned.

On account ofthe recurring downward and upward movement of thefaller'wire or guides during the winding operation, 1t 1sl obvious thata protector cannot be permanently located closely to the Vreceiving sideof the row of cops, be in the way of said guides or of the threads goingfrom said guides to the cops.

It is, therefore, a further purpose of my invention to provide aprotector along the re-A ceiving side of the row of cops on aspinning-mule so mounted and connected as to be positioned closelybeside the copsy during their rapid rotationi that is, during thespinanc therefromv during the winding operation so as notfto interferewith the winding oper- Y p moveback and forth toward and may rom ation.f Y Y It is a further purpose of my. invention to provide means wherebysaid movable/protector on the receiving side of the cops willautomatically move away from its protecting or operative position duringthe winding operation and will return'thereto` at the closeof saidwinding operation or at the v,commencement of the spinning operation,

As effective and simple means for so opi erating the saidk protector Iprovide means whereby the'protector tends to move vaway from operativeor protecting' position, and i Y means connected Vor other part of themachine whereby the lprotector is raised while the faller guide is to.thevfaller wire or guide in raised position incident to the spinning andisV allowed to move eration. Y

. It is a further purpose of my invention to provide a protector alongthe side of the row of cops opposite to the receiving side of the copsor parallel to the hereinbefore described intermittentlv movingprotector,

and in connection with this second protector it is one of theobjects ofmy invention to so mount the said second protector that it may bereadily moved away from the cops for convenience in eXtent as'to cut offlthe current-of. air directly toward or against the sides of` that thepresence Aof these Y as such a protector would 1 solas to be withdrawnVthe doffing or loading or unloading ofthe spinning mule.` Itiwill be Yunderstood that this second protector will benormally in the yoperativeor protective position chiring all the time that spinning. machine isbeing operated, since the protectorupon thati'side is not in the wayofany part ofthe machine during they operating of the machine andmightfbe'per!

The parts of the spinning mule heretofore briefly described are foundwithout material variation inrpractically all the common cotton spinningmachines. To this machine I add and connect my protectingfdevice, asfollows: Upon the back or left hand side 21 of the carriage 6 at itsuppercorner is se cured by means of hinges 22 a normally stationary.protector or shield 23 `extending along the Vrow of spindles and of aheight sufficient to protect the cops to be formed Vupon the spindles.The protector 23 when in normal position is as closeto the cops aspractical in order to leave relatively little air space between theprotector and the row `of cops. This protector normally holds itself inupright and operative position by reason of being placed parallel to therows of spindles and, therefore, inclined slightly toward the front ofthe machine. 1f the inclination of the spindles on any particularmachine is notsuliicient to hold the protector in upright position withsufficient certainty various obvious means, such as springs or holdersmay be provided. This protector on the rear side of the row of spindlesnormally retains its operative position at all stages of the drawing,spinning and winding operations, since it is not in the way of thethreads of cotton being wound upon the cops nor of the fallerbrackets15, norany other part vof the machine. However, for convenience indoliing the machine, the protector is not rigidly secured in uprightpositionbut movably so mounted as by hinges 22 whereby the protector 23may be swung backward and downward affording ready access to thespindles.

Upon the top 23 in front of the spindles or toward the right, asillustrated in the drawings, is niovably mounted another or frontprotector 24, by means of hinges 25, of proper height t0 protect the rowof cops upon the cotton receiving side thereof and extending the lengthof VtheV machine and close enough to the cops 18 to protect them fromappreciable side currents of air. Y This protector is adapted to bepositioned in up- Y Y right or protecting position, as indicated inDuring the downward and then upwardV f ward the front of the machine,the weight of this protector naturally tends -to make the protector falltoward the'top, but ,-I prefer to have further yielding means toaccomplish this movement in order to have the movement take place withpositiveness and certainty. As such means, I attach to this protector 24one endyof a cord 26, which passes forwardly over a roller 27 upon theforward upper corner of the carriage 6 and thence downwardly where it isattached tol a weight`28. This weight in an obvious manner tends towithdraw the protector 24 from its operative position toa ,positionfolded down toward the top of the carriage. As effective means forraising this protector 24 to operative position and holding it thereduring the drawing and spinning operation, I provide straps 29 havingtheir lower ends attached to the upper or free edge of the protector24,and having their upper ends secured to the free end of the fallerbrackets 15 or to the faller wire or guides 16 secured thereto. Thestrap is `of such length that when the faller bracket 15 or its wire 16is 16 moves toward lowered position and atl inthe upper positionincidentl to drawing and spinning the cotton, the strap 29 will bepulled up siiliiciently to draw the protector 24130' operative positionand hold it there. As'soon as the winding operation is to begin thetaller bracket andits guide wire once the protector 24 isreleased andunder the tension ofi lweight 28 moves to withdrawn position allowingthe taller brackets 15 .and thel ialler'wireV or guide V16` to` movedownwardly without interference and without in yany .way interferingwith the threads of cotton passing beneath the taller wire toward thecops 18. Upon the winding operation'being completed, the taller bracket15 rises: carrying .with it the intermittently' moving protector 24:against the tension` of weight 28 `soithat the protectoris'again raisedto operative position by the tiinelthe' rapid rotation of the spindlesVis renewed. This intermittent'positioning of the protector upon thereceiving side of the cops goes on automatically as long as the spinningmachine is in operation. i

It will be seen that I have provided protecting means along both sidesof therow; ot

spindles and the cops thereon, which protectors are always in operativeposition during the rapid'rotat'ion of the spindles and cops, and thatAthe rear lprotector is inv position vat allftimes, except when themachine is being `way ot the vtaller wire guiding the threads of cottonto the cops. While these protectors'- -do not, oi course, preventacce'ssof thefair to the cops during rapid rotation thereof, they do operate'toprevent the actionof air currents'directly toward the sides of the copsin such a way as to prevent the hereinbefore- Vmentioned excessivelyrapid accumulation of dirtor foreign matter upon the outer threads ofcotton upon the cops.

It is obvious lthatV various modilications or Vchanges-may be made inthetorin'or shape-ot the protectors or their operativefor connecting meanswithout departing from the spirit of my invention.

Rests 32 maybe provided upon the top 28 of the carriage 6 to support theprotector 9A when it has fallen far enough away from the row of cops 1S.

It desired to relieve the, taller brackets 15 of the worlr'of raisingVthe front protector 211 from lowered position, arms 30 may be providedas upon the brackets 31 that supports the drawing rollers l, of suchlength and arrangement, that they will engage and v Vforce upward theprotector 9A: as said protector is moved there against when the car` isso raised the tal-len brackets return to npward position and thenthroughstrap29 the protector is easilyfhe'ld up as the `carriage moves awayfrom therollersQ What 1 claim as new and-desire to secure by LettersPatent is:
